BoF: Analyzing Parallel I/O

Date: Thursday, November 20, 2014, 12:15 PM - 01:15 PM

Room: 286-87

Description: Parallel application I/O performance often does not meet user expectations. Moreover, slight access pattern modifications may lead to significant changes in performance due to complex interactions between hardware and software. These challenges call for sophisticated tools to enable scientists and facilities operators to capture, analyze, understand, and tune application I/O. In this BoF we will introduce tools that can help to address this problem for different use cases. We focus in particular on the features of Darshan, SIOX, and Vampir. We also seek to gather feedback from the community regarding I/O challenges and discuss the requirements for monitoring future systems.
